One mole of a compound contains the mass equivalent to the molecular mass or relative formula mass of the compound.
1 mole of iron iii chloride contains a mass of 162.2 g.
Therefore, 50 g will contain 50 g/162.2 g = 0.3083 moles
= 0.3083 moles of Fe2Cl3
Answer: Molarity of a solution : 0.416 M
In our question LiI(Lithium Iodide) is solute and we need to find the moles of LiI.
Given grams of LiI = 27.8g , Volume of solution = 500 mL
Molar mass of LiI = 133.85 g/mol
Moles of LiI = 0.208 mol
To find molarity we need volume of solution in 'L' , so we need to convert 500 mL to L.
1 L = 1000 mL
Volume = 0.5 L
Molarity = or 0.416 M
There are 118 elements in the periodic table.
AICI13 and Ag are the products are formed
Answer: B) Particles can be filtered from a suspension.
Explanation: Colloids are solutions with particle size intermediate between true solutions and suspensions. They exhibit tyndall effect that is scattering of light.
Suspensions have large sized particles which settle when left undisturbed for sometime and thus can be filtered off easily.
The particle size in colloids is less and hence they do not settle under the effect of gravity.
A solution can be homogeneous in which the composition is uniform or heterogeneous in which is the composition is not uniform.
